PR10417 Pass around attributes for supporting DW_OP_{implicit,stack}_value.
Preparation for retrieving the Dwarf_Block that holds the value of an
DW_OP_implicit_value. We need the Dwarf_Attribute that is associated with
the location expression operants. Depends on new elfutils 0.143
functionality. Recognizes, but does not yet handle the new operants
DW_OP_{implicit,stack}_value.
* loc2c.h (c_translate_location): Take an Dwarf_Attribute.
* loc2c.c (c_translate_location): Likewise and pass it on.
(location_relative): Likewise.
(location_from_address): Likewise.
(translate): Likewise and capture Dwarf_Block.
* loc2c-test.c (handle_variable): Pass in Dwarf_Attribute.
* dwflpp.cxx (translate_location): Likewise.
(literal_stmt_for_return): Pass in NULL to indicate no attribute.
